My main research interest is based on what influences resource quality and how resource quality itself is assessed by consumers.

To adress these questions I mainly work with bees, mainly bumblebees, which are able to differentiate between different food qualities and use this ability while foraging.

The main focus of my current work is:

  • Electrophysiological and behavioral experiments to find out which nutrients can be received and perceived by bees
  • Feeding assays to determine the influences of these nutrients on colony performance and quality assessment
  • Finding drivers of the differences in pollen nutrient composition between species
  • Biochemical analyses of pollen

How do bumblebees respond to and regulate food quality? (DFG Project)
